As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises”, “comprising,”, “includes” and/or “including”, when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

[0020] The compositions of the present invention can be formulated according to known methods for preparing pharmaceutically useful compositions. In general, the compositions of the present invention will be formulated such that an effective amount of the bioactive agent is combined with a suitable carrier in order to facilitate effective administration of the composition.

[0021] In accordance with the invention, pharmaceutical compositions comprise active agents, and one or more non-toxic, pharmaceutically acceptable carriers or diluents. Pharmaceutical carriers or excipients may contain inert ingredients that do not interact with the active ingredients, or ingredients that do interact with the active ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the active ingredient with a liquid or solid carrier.

[0022] The present invention is directed to a medical composition and a method for the prevention and treatment of one or more medical conditions having pathological vascular disorder as an underlying cause. The composition according to the present invention comprises a boric acid in a concentration for prevention and treatment of pathological vascular proliferation. Preferably, the boric acid can be present in the range of 0.1%-6% w/v. More, preferably, the boric acid can be present in the range of 0.1%-4% w/v. More, preferably, the boric acid can be present in the range of 0.1%-2% w/v. More, preferably, the boric acid can be present in the range of 1%-4% w/v. Boric acid (H3BO4), also known as hydrogen borate, Boracic acid, orthoboric acid, and acidum boricum, is a weak acid. It will be appreciated that boric acid is the active ingredient of the composition, other ingredients may also be present in the composition which facilitates the administration of the active ingredient. Such ingredients are generally inert and commonly known as excipients or carriers.

[0023] Sodium chloride is one of the most abundant minerals on earth and an essential nutrient for many of the biological processes to absorb and transport nutrients. Sodium chloride representing 1:1 ratio of sodium and chloride ions helps in maintaining the balance of the ionic channels. Potassium chloride has an essential role in the biological processes. Potassium chloride representing 1:1 ratio of Potassium and chloride ions helps in maintaining the balance of the ionic channels. Potassium aluminum sulfate, also known as, potash alum is the double sulfate of potassium and aluminum. The potassium aluminum sulfate can be used in the formulation in a concentration ranging from 0.01% to 0.1%. Chamomile is a well-known medicinal plant. Besides its anti-inflammatory effect, chamomile extract increases cell membrane permeability and enhances the efficacy of boric acid in the formulation by two or three-fold.

[0024] In one exemplary embodiment, the carrier can be selected from a group consisting of distilled water, normal saline, half saline, distilled water, boiled water, medical alcohols including ethyl alcohol, and hydrocortisone solution.

[0025] In one exemplary embodiment, the composition according to the present invention can be formulated as a topical composition, oral composition, parenteral composition, or an ocular composition. The topical compositions including topical gels and solution and topical patches. The oral compositions including tablets, capsules, suspensions, and syrups. The parenteral composition including intravenous injection, subcutaneous injection, sub-dermal, and intramuscular injection. The ocular composition including eye drops, eye gels, ocular implants, and intra-vitreous injection.

[0026] FIG. 1 shows an exemplary embodiment of the composition comprising boric acid in a range of 0.5-4% w/v, Potassium aluminum sulfate in a range of 0.01-0.4% w/v, Potassium chloride in a range of 0.01-0.6% w/v, Sodium chloride in a range of 0.1-0.9% w/v, Chamomile extract in a range of 0.01-5% w/v, and water Q. S.

[0027] FIG. 2 shows an exemplary embodiment of a method 200 for preparing the composition shown in FIG. 1. At step 201, a predetermined quantity of Chamomile extract and water can be taken in a container. The solution can be heated to a temperature of 50-60 degrees Celsius. To the hot solution, at step 202, can be added the predetermined quantities of 0.5% to 4% boric acid, 0.01% to 0.1% potassium aluminum sulfate, 0.01% to 0.6% potassium chloride and 0.1% to 0.9% sodium chloride to form a mixture. The mixture, at step 203, can be continuously stirred while heating to dissolve the ingredients. Once a clear solution is obtained, the heating can be stopped, and the solution can be gradually cooled to room temperature. The solution, at step 204, can then be sterilized and formulated into the desired formulation.

[0028] In one exemplary embodiment, the active ingredient can be formulated into a composition in a neutral or salt form. Pharmaceutically acceptable salts include the salts derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropyl amine, trimethylamine, histidine, procaine and the like.

[0029] In one exemplary embodiment, the composition can be formulated in a form suitable for intraocular injections. According to a first embodiment, the composition is an aqueous solution. Examples of aqueous solutions include, but are not limited to, a solution of boric acid in NaCl, preferably in 0.9% NaCl.

[0030] In one embodiment, sterile injectable solutions can be prepared by incorporating the active compound in the required amount in the appropriate solvent followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum drying and freeze-drying techniques, which yield a powder of the active ingredient, plus any additional desired ingredient from a previously sterile-filtered solution thereof.

[0031] In one exemplary embodiment, the conditions related to pathological vascular proliferation include uveitis, choroiditis, retinochoroiditis, chorioretinitis, retinal degeneration, age-related macular degeneration, retinal detachment, retinal neovascularization, proliferative vitreoretinopathy, retinopathy of prematurity (ROP), diabetic retinopathy, posterior segment trauma, retinal vascular pathologies, endophthalmitis, macular edema, inflammatory pathologies of the retina, systemic pathologies with implications for the retina.

[0032] In a preferred embodiment, the conditions related to pathological vascular proliferation include retinopathy of prematurity, diabetic retinopathy, age-related macular degeneration, central vein occlusion, tumors, and cancers.

[0033] In one embodiment, the method according to the present invention comprises administration of the composition of the present invention in combination with other pharmacological therapies. Combination therapies with other medicaments targeting similar or distinct disease mechanisms have advantages of greater efficacy and safety relative to respective monotherapies with either specific medicament. In one case a VEGF inhibitor can be administered with the composition of the present invention. In another case, Bevacizumab or Aflibercept, or a combination thereof can be administered with the composition of the present invention.
